A Chorlton knifeman was jailed for a minimum of seven years for the attempted murder of a 74-year-old grandmother, today.
David Walters, 23, of Nell Lane Estate, was caught on CCTV spitting in the street after an unprovoked frenzied attack on a pensioner at a bus stop.
Police used a sample of that DNA to connect Walters with the frenzied attack and led to him being imprisoned for a minimum of seven years for attempted murder.
Detective Inspector Lee Price, of South Manchester CID, said: “For every Walters in this world there are a multitude of people who restore your faith in human nature.
“From the strength and fortitude of the victim to the incredible diligence of officers working against the clock, everyone came out of this with huge credit.”
He added: “It was a fantastic team effort which helped ensure we are today talking about a good result and not concentrating on the horrific actions of an extremely dangerous man.”
Walters posted a number of threatening messages on Facebook about a cousin he accused of ‘poking’ his girlfriend on Facebook.
He also made a number of threatening phone calls to various members of his own family, in which he threatened to stab and kill his cousin, before leaving his home in an distressed mood with a 10inch knife.
During his random attack on Mrs Morrison, Walters screamed ‘die, die!’ and ‘I’ll kill you’ as he repeatedly brought the knife down on the horrified victim.
Mrs Morrison managed to struggle to her feet, moved her arms up to defend herself and kicked out at Walters while shouting for help.
He made several attempts to stab her in the head, before the pensioner escaped.
In shock and bleeding heavily from multiple stab wounds, Mrs Morrison managed to stop a passing car and the emergency services were called.
Mrs Morrsion was taken to hospital where she was treated for her injuries including puncture wounds on her body and deep cuts to her hand and lip which later required plastic surgery.
Officers viewed the CCTV footage and spotted Walters spitting onto the pavement near the site of the attack.
The officer at the scene managed to find the saliva and a CSI took a sample for forensic analysis, despite being caught in heavy rain which could have washed away the sample.
The community on the Nell Lane Estate assisted police in their investigations and arrested Walters outside his house the following day.
The DNA sample was fast tracked and Walters was charged while still in custody.
Detective Inspector Price added: “The victim Maria showed immense courage to fight him off in the first place and remarkable strength to make such a recovery.
“I also want to praise the community who supplied us with information and our officers, who acted on it swiftly to ensure Walters was arrested even before we had the DNA sample.
